Description

Linear guide

The invention relates to the technical field of guide rails, in particular to a linear guide rail.

Linear guides, also known as line rails, slide rails, linear guides, linear slide rails, are mainly used for linear reciprocating motions, and can bear a certain torque, can achieve high-precision linear motion under high load; linear guide The function of the movement is to support and guide the moving parts, and make a reciprocating linear motion in a predetermined direction; according to the friction property, the linear motion guide rails can be divided into a sliding friction guide rail, a rolling friction guide rail, an elastic friction guide rail, a fluid friction guide rail, and the like. Linear bearings are mainly used in automation machinery. Linear guides are mainly used on mechanical structures with high precision requirements, such as machine tools, bending machines, laser welding machines, etc.

The existing linear guide rail generally includes a slide rail and a slider, wherein a slide groove is disposed at a center of the bottom of the slider, the slider is spanned on the slide rail through the sliding slot, and a plurality of ball slides are disposed between the sliding slot and the slide rail. So that the friction between the slider and the slide rail is minimized.

However, during the operation of the linear guide rail, foreign matter such as dust and the like are easily infiltrated at the critical section of the slider and the slide rail, and at the top surface of the rail, so that the sliding between the slider and the slide rail is blocked, which increases the relationship between the two. The frictional force may cause the slider to disengage from the slide rail if excessive foreign matter such as infiltrated dust is accumulated.

Therefore, the present inventors have invented the present invention in view of the fact that the idea of creation and creation has been designed with many years of experience, and has been explored and tested by various parties, and has been repeatedly modified and improved.
